One of the busiest travel weeks is approaching - Memorial Day weekend - and a nationwide insurer is advising motorists to update their auto insurance policies before hitting the streets.

Marge Engleman, insurance manager for AAA Auto Club South, explained why this is the case.

"We’re about to hit summer travel season when millions of motorists will be on the roadways for summer vacations and it’s important motorists ensure they are properly protected in the event of a crash," said Engleman. "Oftentimes, motorists make mistakes when purchasing auto insurance that could cost them a lot of money ... Now is the best time to speak with your insurance agent and make sure you have the best coverage before getting on the road this summer."

AAA recommends looking at several things when updating one's auto insurance policy, including shopping around before renewing one's policy, using the same insurer for multiple policies and increasing one's deductible if it's already low. The insurer says a small increase can lead to significant savings in annual premium charges.

Despite rising gas prices, a recent survey conducted by TripAdvisor found 66 percent of respondents planned on driving to a vacation destination Memorial Day weekend.
